This isn't Roblox, there is no scripting, its called Eventing. You hit a brick with a wrench, and go into Events, and do whatever.
[] For doors, Follow some tut on Youtube, or follow these rules
Onatavate > Setname {Door} > Dissapear That is for a door with multiple names, wrench a brick, and set a name at the top.
If its one brick, just do the events
Onatavate > self > Dissapear [] Guns, hit a wrench, and open the Item box, and select DEMO WEAPONS. You can get more and more weapons, vehicles, bricks, ect. Via RTB, which works best if you get the full game.
[] You can not 'Resize' bricks, as I said this isn't Roblox. You have to pick brick by brick and build.
And Don't start with the 1x1x5, or the Blocky Poll bricks found on the bottom of the Bricks Tab, thats spam. And before you start on "ITS ON BASEPLATE" Spam is anything that is worthless, or something that can be changed with a bigger or better brick to lower brickcount or make it better.
[] Marco is a recording device used to record bricks built. You have to look at the bricks in either 3rd person, or first (1st person works best) and you can not change Views or it'l screw it up. You can't move your camera, or put the brick down via Mouse, You have to build it all with the Movements {Eg. Arrow keys to move a brick around} You can't color it with the spraycan either, You have to open that up while the brick is still there, and select a color. Once your done recording, you press the done recording key, which is whatever you set Record Marco and Play Marco is. Then you can put down the brick, and play marco. When playing marco, you need to have the bricks out you used, so that means you can't make a huge house with a billion different kinds of bricks or it'l screw up.
[] If this DOES NOT help, don't post in General Discussions, post in Help.
But before you go there, Look around, watch videos, and research, before just making a topic and getting your butt chewed out. Good luck, You'll need it.
